The coordinates of the vertices of a triangle are A(3, 3), B(6, 3), and C(6, 6). The coordinates of the vertices of its image ar
e A'(-3, -3), B'(-6, -3), and C'(-6, -6). Using complete sentences, describe what transformations would result in this image?

Given:
Shift of 3 units to the left 4 units down.
To find:
The transformation rule.
Solution:
The rule of transformation is
...(i)
Here, a<0 if the figure shifts a units left and a>0 if the figure shifts a units right.
Similarly, b<0 if the figure shifts b units down and b>0 if the figure shifts b units up.
If a transformation represents shift of 3 units to the left 4 units down, then a=-3 and b=-4.
Putting a=-3 and b=-4 (i), we get
Therefore, the correct option is B.
